👉 A grading system is a method of assigning grades to students based on their performance in a specific course or subject. Grades can be given out in multiple ways, such as letter grades (such as A, B, C), numeric grades (such as 90%, 85%, etc.), or percentages (such as 75%, 65%, etc.). Grading systems are often used to measure students' understanding of the subject matter and their potential for future success.
